Useful information in this book is at a minimum. This isn’t a manual or information resource. It did prove to be an entertaining collection of police stories until the writer showed himself for what he was. Plantinga makes a great many movie quotes in this book. And then he makes a point to insult the 45th President of the United States and the millions of people who voted for the President. This is, it would appear, further pandering to the Hollywood crowd, possibly in hopes of gaining employment there as a writer. It might have occurred to Plantinga that there is not a people in the history of the Earth will a lower sense of morals and ethics than the Hollywood industry. This eludes him. I returned this book, because I will not facilitate hate, lies, and unAmerican propaganda.
